javascript - PhantomJS bug in basic script -

this script pretending log in google account (i've made). obviously, doesn't work. there no particular objective here, make work.

var page = require('webpage').create(); page.onconsolemessage = function(msg) {     console.log('console: ' + msg); }; page.open('https://google.com/', function() {     page.injectjs('jquery-2.2.1.min.js');     page.evaluate(function() {         function include(arr,obj) { // functions not part of scraping             return (arr.indexof(obj) != -1);         }         function add(a, b) {             return + b;         }         array.min = function( array ){             return math.min.apply( math, array );         };         function dofirst() {             $('#gb_70').click();             main(1, 0);         }         function dosecond() {             document.getelementbyid('email').value = 'myemail@gmail.com';             $('#next').click();             main(2, 0);         }         function dothird() {             document.getelementbyid('passwd').value = 'p4ssw0rd';             $('#signin').click();             main(3, 0);         }         function dofourth() {             l1 = ['test', 'test2', 'google'];             (var = 0; < 1; i++) {                 if (l1, 'google') {                     console.log('success!');                 }             }             main(4, 0);         }            function dofifth() {             $('.gb_b.gb_8a.gb_r').click()             settimeout(function(){$('#gb_71').click()}, 500);             main(0, 5000);         }         function main(i, j) {             if (i === 0) {                 console.log('launching 0');                 settimeout(dofirst(), j); // connections             }             else if (i === 1) {                 console.log('launching 1');                 settimeout(dosecond(), 5000);             }             else if (i === 2) {                 console.log('launching 2');                 settimeout(dothird(), 5000);             }             else if (i === 3) {                 console.log('launching 3');                 settimeout(dofourth(), 5000);             } else if (i === 4) {                 console.log('launching 4');                 settimeout(dofifth(), 5000);             }         }         main(0, 5000);     });     console('super end');     page.render('google.png'); }); 

at end errors :

console: launching 0 console: launching 1 typeerror: null not object (evaluating 'document.getelementbyid('email').value = 'myemail@gmail.com'')    undefined:7 in dosecond   :22 in main   :4 in dofirst   :18 in main   :29   :30 

i tried many ways , no 1 worked. make work though python , selenium web driver (which real love). time has passed, , has in javascript (to dom/jquery... web compatible).

can me please make work!

edit 1: trying capture screenshot, save empty png.

edit 2: think may hint, when phantomjs test.js, takes long time load , logs everything...

edit 3: changed document.get(...).value = 'blabla' $('#id').val('blabla'); , prints

console: launching 0 console: launching 1 console: launching 2 console: launching 3 console: success! console: success! console: success! console: success! console: success! 

however should prints 1 success, , evidently capture still not work.

for edit 1: trying capture screen

check status make sure page loaded.

page.open(url, function(status) {     if (status !== 'success') {         // exit if fails load page         console.log(status);         phantom.exit(1);     }     else{         // code here     } });
